GAUGE.

Application filed December 10, 192%. Serial No. 754,962.

1 '0 all whom it may concern:

Be it known that I, Gus'ravn 0. EmancsoN, a citizen of the United States, residin at Bemidji, in the county of Beltrami and State of irlinnesotz, have invented iertain new and useful Improvements in Gauges, of which the following is a specification, refer-- ence being had therein to the accompanyin 51 drawing.

This invention relates to mechanics gauges, and has special reference to a carpenters gauge designed particularly for use in the hanging and mounting of doors.

The principal object is to produce a prac tical and efficient gauge of this type.

Other objects and advantages of the invention will appear in the further description thereof.

Referring now to the accompanying drawing, forming part of this application, and in which like reference characters indicate like parts:

Figure 1 is a rear end elevation of one of the improved gauges; I

Figure 2 is a side view of the gauge;

Figure 3 is a front end elevation;

Figure at is a top side view of Figure and Figure 5 is a bottom side view of Figure 2.

1 represents the body portion of the gauge, which is preferably made of light metal construction, substantially square in cross section and of a convenient length for grasping within the hand.

Longitudinally of this body portion or block are formed four substantially equally spaced preferably round holes, in which are longitudinally adjustably mounted the gauge rods 2, 3, i and The rod 2 carries integrally with the inner end thereof the raidally extending marking sprig 6 which projects through the slot or channel 7 in the side of the block opening into the hole therein in which the rod 2 is mounted; there being a thumbscrew S screw threadedly mounted within the block and entering said hole for engagement with the rod 2, so that the latter may be set with the sprig in any desired posit-ion longitudinally of the block. At the forward end of the hole in which the rod 2 is mounted and preferably recessed within the front face of the block, is an adjustable marking sprig 8, it being shown as having three points, and held in position Within the end of the block by a suitable screw 9 with any one of the three points thereupon protruding, as the same retaiably adjustable for such purpose when the screw 9 is slackened and the same may be raised out of its seat in the end of the block. By reference to Figures 2 and 4, it will be seen that the sprig 8 is beveled or sharpened from its innermost edge outwardly, while the sprig 6 is sharpened in just the opposite direction; this being for the purpose of preventing chattering or running of the gauge "hen used upon cross grained or rough surfaces, in that the sprigs being thus sharp ened will tend to draw in opposite directions when flftVGTSlllg a yieldable surface, such wood or the like.

The gauge rod 4 is approximately only half the length of the block 1, is adjustably carried within the block and hold therein by a suitable thumbscrew 10, the latter being carried by the rod 4: and adjustable longitudinally within the slot 11 formed in the block and connnunicating with the hole in which the rod 4. is mounted; the holding of the rod in any desired position in this in stance being accomplished by the impingement of the hub-like portion 12 of the thumbscrew with the side face of the block. The gauge rod 4: is provided at its extendable end with a marking sprig 13 which, when fully retracted, enters a suitable recess in the marginal edge of the hole in which the rod is mounted, so that the sprig does not extend beyond the end thereof. This gauge rod as is obvious may be used for making a single line adjacent the edge of any object, as a common gauge is used.

In the same hole with the rod 41-, but in the opposite end of the block from that in which the gauge rod 4; extends, is mounted the short rod 14., it being held therein in any desired position by a suitable thumbscrew 15 made to impinge same. Upon the end of the rod is a flat plate 16, one edge 17 of which is in the same plane with the adjacent face of the block and through which face the sprig 6 0f the rod 2 protrudes. This blade is for the purpose of operation in conjunction with the sprigs 6 and 8, either singly or together. For example, in setting the gauge for marking the position of a striking blade in a door frame, assuming that the lock is in position in the door, the gauge is held with the sprig 8 against the edge of the door and the plate 16 adjusted by movement of its carrying rod 1 1 to proper alignment with the striking face of the bolt of the lock, when the thumbscrew 15 may be turned to retain such position of the plate, thus giving the proper spacing between the plate and the sprig S. hen this is done the sprig 6 may be adjusted by measurement to the proper width of the striking plate so that when the gauge, thus set, is used upon the door frame, the proper positioning and alignment of the striking plate is readily determined. lVhile this explanation applies to the setting of a strike for doors, it is apparent that when. any two parallel lines are desired in respect to a projecting edge, the sprigs may be set the desired distance apart and the sprig 8 from the plate 16 the desired distance, when such alignment on the object may be readily accomplished for purposes other than that mentioned in the foregoing.

The rod 5 is relatively shortand has a radially extending externally screw-thread ed pin 18 centrally thereof which extends through the slot 19 formed in the face of the block connnunicating with the hole in which the rod 5 is mounted, said slot being the entire length of the block. Mounted upon the pin 18, externally of the block, is

an L-shaped metal gauging member 20, which extends about the corner of the block adjacent the slot 19, and is in length substantially the fullwidth of that side of the block through which the sprig 21 on the end of the rod 3 protrudes, said gauging member acting in conjuction with the sprig for common gauging purposes, or with both sprigs 21 and 23 for making a double line. Upon the pin 18, externally of the gauging member 20 is a thumb-nut 22 for holding the gauging member, as is obvious, longitudinally of the block. In the front end of the block and protruding from the opposite face thereof to that from which the sprig 8 protrudes is a similar adjust able sprig 23, it being recessed into the end of the block and adjustably held therein identical with the" sprig 8 and located in direct alignment of the sprig 21 on the rod 3, and these two sprigs 21 and 23 are sharpened in the same manner as the sprigs G and 8, that is with divergent inner faces, and with the same object of attainment.

Thus we have two more marking sprigs adjustable in respect to each other and in respect to a gauging men'iber extending beyond the side face of the block inwardly of the longitudinally adjustable sprig, said gauging member also being longitudinally adjustable of the block so that two parallel lines may be lifted or taken from any one object and delineated upon another, as for example in the installation of a door lock or the like.

The rod 3, carrying-the sprig 21, is retained in any desired longitudinal position by the use of the thumb-screw 24.

Having thus described my invention, what 1 claim and desire to secure by Letters Patent. is:

A. carpenters gauge of the type described coniprising an elongated body portion carrying longitudinally adjustable gauge rods therein, one of said rods carrying a gauging member protruding from one side face of the body portion, another of said rods carrying a gauging member protruding from the end face of the body portion, and a fixed gauging member intermediate of the adjustable gauging members.

In testimony whereof I hereunto afiix my signature. I
